Technovit 9100 NEW is a polymerisation system
based on methyl methacrylate (MMA) which hardens at low
temperature. It has been specially developed for embedding
mineralised tissues with extensive possibilities of staining
for light microscopy.

The chemical polymerisation of Technovit 9100
NEW takes place under the eclusion of oxygen with the aid of
a catalyst composed of a peroxide and an amine component.
Additional components such as PMMA-powder and a regulator
allow for a controlled polymerisation by tgemperatures
between -8 and -20℃, which gurantee a dispersion of the
heat generated during polymerisation. The polymerisation time
is betgween 18 and 24 hours ysubg a vikyne between 3 and 15
ml for the above tempemperature range. After necessary
pretreatment of the tissue - all current staining methods can
be applied to the MMA-sections after removal of the polymer.
These include classical staining as well as immuno- and
ezyme-histochemistry. In-situ hybridisation (ISH) techniques
can also be performed.

The polymerisation system Technovit 7200VLC -
developed for classical cutting-grinding and micro-grinding
systems (contact-line technique) - retains its proven range
of applications and is especcially recommended for use with
cemented endoprostheses and implants.

Technovit 7100 and Technovitg 8100 which are
based on glycol-methacrylate are especially suitable for
small organ biopsies with thin- and semi-thin section
techniques and have a well-known wide spectrum of
applications.

The embedding systems complement eadh other
with respect to the diagnostic and scientific to be answered.

System Components of
Technovit 9100 NEW

Basic solution (stabilised) 1000 ml

PMMA-Powder 120 g

Hardener 1 8 Sachets a 1 g

Hardener 2 10 ml

Polymerisation regulator 5 ml

PMMA-Granulate, EXAKT 500 g

1. Basic Solution

The basic solution Technovit 9100 NEW is
composed of monomers-organic molecules with at least one
carbon-carbon double bond. The stabiliser contained in the
kit is responsible for the storage-stability. Hydrophilic
properties are improved by addition of a special
hydrophilic-generating agent. Technovit 9100 NEW can be used
either in the stabilised or destabilised form.

2. PMMA-Powder

The powder is an internal filler and is made
up of PMMA-micropellets. It is used

-to reduce the polymerisation-shrinking
effect markedly

-to reduce the heat generated during the
polymerisation process as well as

-to improve the quality of the polymerised
product.

3. Hardener 1

Hardener powder is the one of the components
of polymerisation initiation system. It is a derivative of
dibenzoyl peroxide which - in combination with Hardener 2 -
starts the polymerisation reaction.

4. Hardener 2

This liquid hardener is the second component
of the initiation system. It works catalytically upon hardner
1 to allow a controlled polymerisation even at temperatures
below 0℃。

5. Regulator

The regulator is composed of a reactive
organic compound which allows a controlled polymerisation -
even with large volumes of polymer - without large increases
in the temperature during the polymerisation reaction.

6. PMMA-Granulate,
EXAKT

This granulate acts as an additional internal
filler when larger amounts(500-1000ml) of polymer are to be
used - as for example in the case of a femur shaft with
non-cemented endoprostheses. The amount of monomer (basic
solution) is thereby reduced, at the same time making the
polymerisation easier to control.
